[0002] PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin cross section. PE has excellent resistance to most domestic and industrial chemicals. Due to its unique advantages, PE pipe is widely used in building water supply, building drainage, buried drainage pipes, building heating, gas transmission and distribution, gas transmission pipes, electrical and telecommunications protective casings, industrial pipes, agricultural pipes, etc. At present, during the use of PE pipes, it is bent according to environmental needs, so a bending device is needed. For this purpose, China has authorized a utility model patent (publication number: CN216804396U) to propose a PE pipe processing bending device. The PE pipe is bent by heating and softening the PE pipe, so that the toughness of the PE pipe is increased when the PE pipe is bent, and then the hydraulic rod drives the bending block to bend the PE pipe.
[0003] In the actual production and processing process, it is often necessary to process PE pipes of different specifications. During the use of the above-mentioned device, the distance between the two guide wheels used for guiding is not easy to adjust. Therefore, when it is used for PE pipes of smaller and larger specifications, it is not easy to effectively achieve the guiding effect, which limits the scope of application of the device. Therefore, in view of the above problems, a pipe bending device for PE pipe processing is proposed. Utility Model Content
